Scrum is: Lightweight, Simple to understand and Difficult to master״, according to the Scrum Guide.

So.. Are you the scrum master? You have a big a challenge! The scrum guide itself says your role to master Scrum is difficult..

What makes it is so difficult? People! This role is focused on people. Influencing people without power and without authority. And as a people's person you know that being efficient doesn't make you necessarily effective. That's a hard sell.
